Size & Maneuverability

Both the 2025 RDX and the 2025 MDX have compact dimensions and are easy to handle across bustling city streets, but the five-seater RDX is more compact. This crossover is built on a 108.3-inch wheelbase and has a total length of 187.4 inches. With a width of 74.8 inches, it can easily fit in tight spots. It also has a ground clearance of 8.2 inches, which means it can handle asphalt roads and dirt paths alike.

The seven-seater MDX is built on a 113.8-inch wheelbase and has a total length of 198.4 inches. This SUV is about four inches wider than the RDX, and it has a ground clearance of 7.3 inches, features that make it a better choice for urban driving and road trips.

Engines & Performance

While both models have sport-inspired powertrains, the MDX is more powerful. This SUV comes standard with a 290-hp 3.5L V6 engine, while the range-topper Type S trim brings more sportiness with a turbocharged engine that pumps out 355 horsepower. All RDX models draw power from a 272-hp 2.0L VTEC Turbo engine.

With the base powertrain, the MDX impresses with EPA-estimated fuel economy ratings of up to 26 MPG on the highway. The RDX provides up to 27 MPG on the highway and 23 MPG combined.

Interior & Cargo Capacity

With a passenger volume of 104 cubic feet and 42 inches of legroom in the front row, the RDX delivers a comfortable driving experience. The second row is also perfectly sized for adults, offering 38 inches of legroom. Behind the rear seats, the main cargo area boasts a volume of 29.5 cubic feet, which can expand up to a maximum of 79.8 cubic feet behind the front seats.

The MDX has an ample cabin with 41.6 inches of legroom in the front row, 38.5 inches in the second row, and 29.1 inches in the third row. The second-row bench has seats for three and boasts a multifunctional design with a removable middle seat, so you can easily turn the bench into lavish captain's chairs.

5 Reasons the 2026 Acura Integra Type S Still Gets It Right

Performance cars have become extraordinarily clever. They have also become heavier, more complicated, and increasingly determined to put a screen or electronic setting between the driver and the machinery. The 2026 Acura Integra Type S takes a more appealing route. It has serious, Turbocharged power, a manual gearbox, useful technology, and enough practicality to function beyond a Sunday morning drive. For drivers around Grapevine and the Dallas-Fort Worth area, these 5 characteristics explain much of the Type S appeal. 1. The Engine Has the Numbers to Back It Up The 2026 Integra Type S uses a 2.0L VTEC® Turbo engine producing 320 hp and 310 lbs. ft. of torque. Those are substantial figures for a compact performance car, but the more important detail is how Acura lets the driver access them. The engine is paired exclusively with a close-ratio 6-speed manual transmission. There is no automatic alternative waiting farther down the options list. The Type S assumes its buyer wants to participate, and Acura has built the powertrain around that idea. Its Turbocharged output gives the Integra Type S the performance expected of a modern sport compact without changing the basic character that makes this sort of car entertaining. 2. Acura Kept the Manual Manual transmissions are becoming unusual enough that simply offering one deserves attention. Acura goes further by making the 6-speed manual central to the Type S experience. A lightweight flywheel allows the engine to gain revs rapidly, helping create the responsive character expected from the VTEC® Turbo powertrain. Rev-Match Control can smooth downshifts by matching engine speed during gear changes. This is technology assisting a mechanical experience rather than replacing it. Drivers can still choose their gear, work the clutch, and decide how they want to use the engine's performance. That distinction gives the Type S much of its personality. 3. Sport+ Changes More Than a Graphic Drive modes can sometimes amount to little more than different dashboard graphics. Sport+ in the Integra Type S makes changes the driver can use. Selecting Sport+ stiffens the dampers for sharper responses and opens the Active Exhaust Valve. The result is a more aggressive exhaust note and a chassis setting aimed at enthusiastic driving. It also gives the Integra useful flexibility. The most aggressive settings do not need to be engaged for every trip across Grapevine. When the road becomes more interesting, Sport+ allows the Type S to reveal another side of its character. 4. The Wider Body Is Doing a Job The Integra Type S is more than 2 inches wider than the standard body, and the additional width gives it a noticeably more planted appearance. Yet the exterior changes have engineering behind them. Large front openings direct air toward the intercooler and brake ducts, helping manage cooling during harder driving. At the rear, a diffuser contributes to aerodynamic stability by helping reduce lift. Chicane™ LED daytime running lights and taillights provide the recognizable Acura lighting signature. Taken together, the Type S design communicates its performance without relying on decoration that serves no useful role. 5. Performance Hasn't Consumed the Cabin The cabin follows the same philosophy. Bolstered sport seats provide additional support and feature Type S-specific details, but the interior retains the equipment expected from a modern Acura. A 10.2-inch digital instrument cluster places driving information directly ahead, while the available head-up display can project vehicle speed and AcuraWatch™ information onto the windshield. Wireless charging and rear USB ports add useful connectivity for trips beyond a short back-road run. That balance is important. The Integra Type S remains a car you can enjoy when the road opens up without becoming tedious when traffic closes it again. The Type S Is Best Experienced from the Driver's Seat The strongest argument for the 2026 Acura Integra Type S is not one specification. It is the way the pieces work together: 320 hp, 310 lbs. ft. of torque, a close-ratio manual, adaptable suspension settings, functional aerodynamics, and a cabin that remains usable. Drivers interested in experiencing that combination can explore the Integra Type S inventory and other new Acura models at Grubbs Acura in Grapevine. Compare available vehicles, research the Integra lineup, and schedule your Acura Integra Type S test drive online to find out how those 5 highlights translate to the road.

That low-end torque is complemented by a 10-speed automatic transmission with sequential SportShift® paddle shifters, giving you utterly seamless shifts and heart-thumping acceleration—along with a more engaged experience behind the wheel. Adaptive Air Suspension for a Refined Ride One of the standout features of the 2026 Acura MDX Type S w/Advance Package is its adaptive air suspension with auto leveling.

This brake-by-wire system electronically measures driver pedal input, and a control unit commands a servo actuator to generate the required hydraulic brake pressure at each wheel.

2026 Acura MDX A-Spec

5 Features That Give the 2026 Acura MDX A-Spec Its Edge

There is a temptation with sporty versions of large SUVs to bolt on darker wheels, add a badge, and declare the transformation complete. The 2026 Acura MDX A-Spec® goes further than that. It combines its sharper visual treatment with a 290 hp V6, standard Super Handling All-Wheel Drive™, a 19-speaker audio system, and seating for up to 7. For drivers around Grapevine, TX, these 5 features explain what the A-Spec® brings to Acura's 3-row SUV. 1. The A-Spec® Treatment Continues Inside The A-Spec® cabin has enough distinctive equipment that you won't need to check the badge on the tailgate to remember which MDX you're driving. Heated and ventilated front sport seats use perforated Milano premium leather and Ultrasuede® trim, with choices including Ebony and Red. A flat-bottom leather-wrapped sport steering wheel, metal sport pedals, contrast stitching, and stainless-steel speaker grilles continue the theme without turning the interior into a costume. Seating remains available for up to 7, while the removable second-row center seat can create a captain's-chair-style arrangement and open a clearer route to the third row. 2. There are 19 Bang & Olufsen® Speakers A Bang & Olufsen® Premium Sound System is standard on the MDX A-Spec®, and Acura has not been stingy with the hardware. The system employs 19 speakers and 16 channels, along with Acoustic Lens Tweeters, 3D Sound Control, and speakers mounted in the headliner to create a more enveloping listening experience. Wireless Apple CarPlay® and Android Auto™ are standard as well, allowing compatible smartphones to connect without a cable, while a standard wireless charging pad provides a convenient place to keep a compatible device powered. 3. The Exterior Gets More Than a Different Set of Badges A-Spec® models ride on 20-inch Shark Gray 10-spoke alloy wheels fitted with 255/50 R20 high-performance all-season tires. Gloss Black exterior accents, A-Spec® badging, and unique front and rear styling provide additional visual separation from the MDX and Technology packages. Acura's lighting does some of the work as well, with Jewel Eye® LED headlights at the front and Chicane™ LED daytime running lights and taillights. The result is a sportier interpretation of the MDX without changing the SUV's underlying 3-row proportions. 4. SH-AWD® Is Standard, Not an Option Box Every 2026 MDX A-Spec® uses Acura's 3.5L aluminum-alloy V6, producing 290 hp and 267 lbs. ft. of torque. It is paired with a 10-speed automatic transmission with Sequential SportShift paddle shifters and standard Super Handling All-Wheel Drive™. SH-AWD® can vary power distribution between the front and rear axles while also actively distributing torque between the rear wheels, giving the system a role during acceleration and cornering instead of simply waiting for traction to disappear. A double-wishbone front suspension and multi-link rear suspension handle the chassis duties, while properly equipped SH-AWD® models can tow up to 5,000 lbs. 5. Google Gemini Joins the Dashboard A standard 12.3-inch color touchscreen includes Google built-in with Google Gemini, Google Maps, and compatible apps through Google Play. Gemini allows occupants to use natural voice commands for tasks such as finding destinations, adjusting compatible vehicle settings including climate control, and asking questions about the vehicle. A 12.3-inch Precision Cockpit™ digital instrument display is also standard. AcuraWatch™ adds driver-assistance systems including Collision Mitigation Braking System™, Adaptive Cruise Control with Low-Speed Follow, Lane Keeping Assist System, Traffic Sign Recognition, and Traffic Jam Assist.
